1. A user equipment comprising:
a transceiver;
a memory; and
a processor communicatively coupled to the transceiver and the memory and configured to:
transmit, via the transceiver using a first frequency band, a metric message indicative of the user equipment being in a coverage-limited area corresponding to a serving cell;
receive, via the transceiver, a positioning signal configuration message in the first frequency band, the positioning signal configuration message indicating a first configuration of a downlink reference signal and a second configuration of an uplink reference signal;
receive, via the transceiver using the first frequency band, the downlink reference signal; and
transmit, via the transceiver using a second frequency band, the uplink reference signal, the second frequency band comprising frequencies below a lowest frequency of the first frequency band.
